application inea Aprii 1e, 1903.

To o'fZZ whom it may concern:

Be it known that I, EUGENE ORA DANIELS, a citizenof the United States, residing at Toledo, in the county of Lucas and State of Ohio, have invented certain new and useful Improvements in Gas-Burners; and I do hereby declare the following to b e a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification. 1

My invention relates to the class of burners employed in the consumption of natural or artificial gas, is especially adapted and designed for use in connection with the ordif nary cook-stove, and can be used either for cooking or heating purposes.

The object of my invention is to provide an apparatus having a series of burners adjust-A ably arranged Within the stove with which it is connected in such manner as to cause the combustion to take place and the heat therefrom to be evenly and perfectly distributed to the parts of the stove desired to be heated' and also to provide a burner of the'class described that is simple and Anovel in its construction and arrangement of parts and inl which the ports for the admission of air to the mixing-chambers are so arranged with reof a portion of one of the burners adaptedvr to bel used in my invention, showing the gas-v escape openings therein. Fig. 3 is a transverse Vertical sectional viewof my invention `'With theY lid-burners removed, taken on the dottedline .fr in Fig. 1 and showing the Serial No. 152,288. (No modeld same mounted' within the iire-box of a stove and equipped with adjustable front and rear burners;r and Fig. 4 is a modified construction of a portion of the Asupply-pipe leading to the rear lid-burner.

Referring to the drawings, A represents the grate, B the casing interposed between the oven andv {ire-box, and C the Water-front, of an ordinary cook-stove in which my invention is adapted to be used.

In Fig. 1 of the drawings, 1 represents a single standard or supporting-bracket having a series of transverse openings therein arranged on a horizontal plane and adapted to receive and support the transmission-pipes 2, 3, 4, and 5, which lead therefrom to the front or Water-heating burner 6, the lid-burners 7 and 8, and the rear or oven burner 9,v respectively. Each of these pipes connects at its outer end with an independent valve lO, by

trolled.

The transmission-pipes 2 and 5, which are connected with the valves 10 by having their ends slipped tightly over the gas-discharging nipples 12, are loosely inserted in and project through the bearings or openings provided for their reception in the standard 1. To the other end of the pipe 2, which terminates at a point intermediate of the burners 7 and 8, the leg or elbow of the T-shaped burner 6, thecross-piece of which is horizontally disor escape-openings through which the gas is discharged to the atmosphere. The end of the pipe 5 which projects through the bear ing in the standard 1 may be prolonged and provided with apertures to form an elongated horizontal Ystationary burner 9, as shownvin Fig. 1, or it may be shortened and equipped with a T-shaped burner 9', similar to the burner 6, as shown in Fig. 3. To retain these burners in proper adjustment Within the standard 1, I provide the binding-bolts 13 13.

It willbe seen by reference to Fig. 3 that the burners 6 and 9' may be placed in close juxtaposition to the leg of the standard 1 or swung outwardly and upwardly-therefrom, as it is desired to transmit the heat to the lower means of which the discharge of gas from the s common feed-pipe 1l to the said pipes is con- L posed and provided with a row of apertures IOC or upper portion of the stove or to adapt it to be placed in stoves having hre-boxes of various sizes.

The transmission-pipe 3 is screw-threaded at one end to its valve 10 and at its other end to the standard 1, whereit cotnmunicates with an obliquely-disposed vertical bore 14 in said standard, which passes to the lower portion thereof and communicates with a rearwardlyextending conduit or pipe 3', leading to the mixing-chamber 15 of the rear lid-burner 8. If it is desired, the pipe 3 may pass entirely through the standard 1 and communicate with the pipe 3' through the elbow 3", as shown in Fig. 4.

The transmission-pipe 4 is connected with the valve 10 in the same manner as the pipes 2 and 5 and has its other end threaded tothe standard 1, where it communicates with the front lid-burner 7, which is centrally mounted on said standard through the obliquely-disposed vertical bore 16.

I It will be apparent that by loosening the binding-bolts 13 13 the pipes 2 and 5, with their respective burners, may be easily disconnected from their valves and removed from the standard 1, thus enabling my invention to be used as either a two, three, or four burner apparatus.

In order to obtain the highestdegree of heat from the combustion of the gas as it is expelled through the orifices of the burners, it is necessary that it should be properly diluted and mixed with air before such combustion takes place. To accomplish this, I provide the air-induction ports 17, adjacent to the nipples 12 in each of the transmission-pipes 2, 4, and 5, the said nipples being provided with a restricted central escape opening through which the gas is discharged into the said pipes or mixing-chambers, where it is mixed with air as it is drawn through said ports. These ports are a sufficient distance from their respect-ive burners to enable the ygas and air to be properly mixed before they reach the burners. It is known that the pressure of gas after itI has been discharged into the mixing-chamber of a burner is reduced about one-fourth by every right-angled turn in the pipe throughwhich it is required to pass, and I therefore locate the mixing-chamber for the burner 8 directly under said burner, as shown at 15in Fig. 1, instead of adjacent to its valve 10. The mixing-chamber 15 is semispherical in form, having its bottom or fiat portion open to admit the air thereto, the said bottom being adapted to rest upon the grate A of the stove. The burner 8 is supported above the chamber 15 and communicates therewith by means of the pipe 18, which is screwed into said chamber. Within the chamber 15 is formed a tubular casing 19, which communicates with the supply-pipe 3 through an opening in the side of the chamber 15, into which the said pipe is threaded,

and is provided with a restricted escape-opening 2O in its upper portion in vertical alinement with the pipe 18, into which it is adapted to discharge the gas, where it is mixed with air drawn in through the bottom of the chamber 15.

In the construction of my invention I have endeavored to provide an apparatus that might bev readily and easily fitted and adjusted to any cook-stove of ordinary size without the necessity of v,mutilatingor breaking the stove in any way. By the use of the standard 1 the transmission-pipes 2, 3, 4, and 5 are supported on a level with and are enabled to pass through the opening provided in the stove for the door, thus avoiding the necessity of cutting an opening therefor.

It is obvious that such changes in the form, proportion, and minor details of construction of the parts as fairly fall Within the-spirit and Scope of my invention may be made without departing from the vspirit or sacrificing any of the advantages thereof.
